Abstract
The present study was undertaken with the aim to carry out Patent Analysis of selected Indian
manufacturing firms and to study the relationship between Patent Data and Firm Performance.
Five major manufacturing sectors namely, Automobile, Consumer Goods, Energy, Industrial
Manufacturing and Pharmaceuticals were included in the study. Period of analysis was 10
years i.e. from 2004-05 to 2013-14. Patent Analysis consisted of Patent Applications, Patents
Granted, Backward Citations, Forward Citations and Total Citations. Measures of Firm
Performance included in the study were Profit after tax as a percentage of Total Assets, Sales,
Sales Growth and Tobin’s q. The results of the study indicate that Pharmaceutical sector has
filed maximum number of Patent Application and maximum Patents were Granted to this
sector. There was a significant difference among various sectors on the basis of Patent Data.
Results of correlation analysis revealed that there was no definite relationship between Patent
Data and Firm Performance as the results varied across the sectors. There was positive and
significant correlation between Patent Data and Sales for Pharmaceutical and Energy Sector.
There was evidence of positive and significant relationship between Profit After Tax as a
percentage of Total Assets and Patent Applications as well as Patents Granted but small value
of correlation coefficient pointed towards very week relationship.
